The multi-resolution multicast service is an emerging service for future generation communication systems, supporting different service qualities for receivers with different capabilities. Under such a scenario, the radio resource arrangement becomes very complex but is important in order to enhance the overall system throughput. For multi-resolution multicast OFDM systems, we proposed an adaptive...
OFDM is an attractive solution for the design of future wireless communications due to its robustness to dispersion in multipath environments. Additional diversity gains can be realised by OFDMA by exploiting not only the temporal fading, but also spectral fading, that can result in higher rates due to increased diversity. A scheduler exploiting multiuser diversity imposes strict feedback requirements...
Recent studies report that in wireless networks, schedulers exploiting multiuser diversity can substantially enhance the maximum throughput of the overall system. In this paper, we focus on a scheduler which maximizes the throughput of the overall system by exploiting multiuser diversity and is combined with adaptive modulation and coding. We numerically study the statistical time-access fairness...
